Should not change valve assessment practice; leaves open whether energy loss metrics improve outcomes over standard measures.
Does measuring energy or power loss per unit flow improve the assessment of haemodynamic function in patients with diseased and prosthetic heart valves compared to current methods?
Measuring energy or power loss per unit flow provides a more useful assessment of heart valve haemodynamics than traditional resistance measures.
